Having some minimal UI on the tracker so messages could be sent back to it from the Net Control Station position would be a plus.

You've just described a Kenwood D7 or D72 or a Yaesu VX8......

By the time you:


-     take a basic RX/TX "data radio" something like this

     <https://www.argentdata.com/catalog/product_info.php?products_id=110>

-    add a full send & receive    modem/TNC    such as a TinyTrack 4 or Tracker 3,

-    add a keyboard & display, a tablet, or a small laptop for a send/receive 
user interface

-    and finally add a GPS receiver


you have basically re-invented the Kenwood or Yaesu APRS handheld -- probably 
in a much bulkier package.
